title: Effective tooth bleaching in 5 days: using a combined in-office and at-home bleaching system.
abstract: This article compares the bleaching efficacy of a combined at-home and in-office system with that of an in-office system alone. Twenty people participated in the study. Ten of these participants were treated with an in-office 35% carbamide peroxide bleaching product in 2 visits of 15 minutes each. The remaining participants were treated with a combination at-home and in-office system that included a 15% carbamide peroxide at-home bleaching agent. After 5 days of treatment, the participants using the combination system demonstrated increased tooth whitening compared to those using the in-office system alone. Based on the sample size (20 patients), statistical significance was achieved.
